DEEP LOW TEMPERATURE CASE HARDENING

The depth of the altered surface layer produced by low temperature carburizing a stainless steel workpiece can be significantly increased by introducing fissures or interstices into the workpiece's surface before low temperature carburization is completed. La profondeur de la couche superficiel...

Beschreibung
Zusammenfassung:	The depth of the altered surface layer produced by low temperature carburizing a stainless steel workpiece can be significantly increased by introducing fissures or interstices into the workpiece's surface before low temperature carburization is completed. La profondeur de la couche superficielle modifiée par une cémentation à basse température d'une pièce en acier inoxydable peut être sensiblement accrue par l'introduction de fissures ou d'interstices dans la surface de la pièce avant achèvement du processus de cémentation à basse température.
